SPECIFICATION forming part of Letters Patent No. 276,934, dated May 1, 18831.

Application filed November 20, 1882. (No model.)

To all whom t may concern:

Be it known that I, DoLPHUs TORRES'. of the city, county, and State of New York,have invented an Improvement in Emergency- Brakes for Railway-Gars, ot' which the followingis a specification.`

My invention relates to a brake apparatus intended to secure the application of the brakes upon cars which may be accidentally detached from the train,as by the breaking of the coupling-link between the cars. To .this end Iconnect the brake rod or chain of one car with the car immediately in front through the medium ot' a separable clutch. In one embodiment of the invention the clutch is inclosed in asleeve or open-,ended box or socket fixed to the car to which the brakes are applied, the extremity of the clntchconnection being hooked to the preceding car and the parts so constructed and combined that on the severance of the car-coupling the clutch-connection will, by the separation of the cars be drawn through the fixed sleeve, so as to apply the brakes and at the same time permit the separation of the clutch, one member of which is carried away bythe forward car, while the other member is caught by the forward end of the sleeve, so as to retain the brakes in their .strained condition. Under another embodiment ot' the invention an ordinary hand staff or windlass forms the means of attachment for the chain connecting with the preceding car, the connectin g or emergency chain, which is attached to the preceding car, being so coiled on the hand-brake stati" or windlass as to rotate the sameand draw on the lbrakes when the preceding car moves away. The emergency-chain then escapes from the windlass, and the latter is caught by its pawl or ratchet, so as to hold the brakes on. l

In the accompanying drawings, Figure 1 is a side elevation of adj acent parts of two connected cars, showing the application of theinvention. Fig. 2 is an end view, on a larger scale, of axed box or sleeve within which the automatic-brake appliance works. Fig. 3 is a longitudinal section ofthe apparatus, also on a larger scale. Fig.4'is a longitudinal section showing the apparatus in action, as on the accidental breakage of a carcoupling.` Fig. 5 is a longitudinal section of a clutch of modi- Iied form. Fig. 6 is an elevation illustrating another modification, in which the clutch or connection consists or" an emergency -chain connected with the preceding car and coiled on a hand-brake staff or windlass, so as to wind up the brakes when drawn oti.` l

The xed sleeve or box l, Figs. l to 5, inclusive,may consist oi' a rectangular tube one foot in length, one by three inches in dialneter, and open at both `ends. At its rear end is au inturned lug, 9, to prevent the clutch or coupling-piece pulling out backward. One of the boxes l is iixcd to the bed'frame ot the car or at or near"'each end, and contains a clutch consisting of two members, 2 3, which are held in lock or engagement by the said fixed sleeve 1. The fixed sleeve'also contines a'spring, 4, the expansion of which, on escaping from the sleeve, permits or causes the disengagement ofthe clutch members 2 3. The clutch-piece 2 is attached to a pull-chain, 5, connected with a lever, 1.1, of the. brake system' of the car to which the sleeve l is fixed. The other clutch-piece, 3, is attached to the emergency-chain 6, terminating in a ring, 7, which, 'when at the rear end of the car or out ot'use, may be caught on a hook at the end of its own car. The ring 7 of the emergencychain 6 at the forward end ot each car is, on making up the train, dropped over the head of the coupling or any other pin on the car ahead. The engaging faces of the clutch members 2 3 are shown at 10 10. The clutch-piece 2 is further provided with a shoulder, 8, which, in

the normal position of the apparatus, enga-ges with the internal lug, 9, at the rear end ofthe xed sleeve 1, preventing the escape of the clutch backward and affording a bearing or fulcrum-point at either end of the car to permit the straining ofthe brakes from the other end.

It will now be apparent that in the event of the breaking ot' a coupling the forward car, in separating from that behind it, will draw the clutch 2 3 through the iixed sleeve l. As it emerges therefrom the spring 4 expands, releasing the member 3 from the piece 2, and at the same time throws the shoulder 8 into engagement with the forward end of the sleeve, so as to hold the brakes in the strained condition to which they are drawn, while the emergency-chain goes with the `forward car without any breakage of the apparatus or violence thereto.

In the embodiment ot' the invention repre-A ICO sented in Fig. 5 the clutch member 2 consists of two pieces hinged together and confining the arrow-headed piece 3 between them while within the sleeve and expanded by the spring 4, so as to release the piece 3 and cause the two shoulders 8 8 to engage the front of the sleeve when drawn out. I have used both forms of the devicein practice with good eifect.

A simple mode of applying my invention of an emergency-brake in connection with an ordinary hand-brake staff or windlass is illustratedfin Fig. 6. The emergency-chain 6 is here coiled on the hand-shaft or windlass 12, so as in being drawn off to wind the ordinary brake-chain thereon. The shaft, being then caught by the spring-ratchet 13, holds the brakes on while the chain 6 is pulled off the pin 14, on which itwas caught on said shaft, and escapes without damage. In either case the brakes are instantly applied to the forward car of an accidentally-unconpled section of a train, and the checking of the speed of this forward car may cause an automatic application ot' the brakes to the following cars b y a customary momentumbrake apparatus. In case it is desired that the brakes shall be applied to the last carin front of a severed coupling, the emergency-chain 6 may be connected with a like chain upon the preceding car7 instead of to a pin thereon, and so secure an automatic application of the emergency-brakes to the two cars in case of an accidental severance of the train.

Y Having thus described my invention, what I claim isfcar adjacent to therst-mentioned car.n

2. ,In a separable coupling for railway-brake systems, the combination, with a sleeve or other similar device provided with stops or lugs, substantiall y as described, of aseparable clutch composed of two members arranged to engage with each other, one ot' said members being connected willi the brake mechanism and provided with a device for engaging with the stops ot the sleeve, and also with a spring for insuring such engagement, and the other member being connected with the car adjacent to that carrying the sleeve. s

3. The combination of the clutch or coupling 2 3 andy spring 4 and fixed sleeve 1, substantially as and for the purpose set forth. 4. The combination of the chains or rods 5 and 6 with the couplings 2 and 3, substantially as and for the purposes set forth'. t DOLPHUs YTORRI-JY.
